Dublin-listed Merrion Pharmaceuticals has announced plans for 20 redundancies at its Citywest headquarters in Dublin before the end of the year. The lay-offs are part of a continuing review of its business. Merrion says it plans to focus on research and development and outsource some other activities. The company said it made a loss of just over €2m in the first half of this year, compared with an €800,000 loss in the same period a year earlier.
